Treatment of 2,6-disubstituted-4-t-butylphenols with thallium(III) trifluoroacetate in either trifluoroacetic acid or carbon tetrachloride as solvent results in loss of the 4-t-butyl substituent as isobutene and formation in high yield of the corresponding 2,6-disubstituted p-quinones. Possible mechanisms for this novel reaction, which probably proceeds via the intermediacy of a hydroquinone or hydroquinone

synthetic protocol to realize aromatic perfluoro-tert-butylation. The key to the success is the identification of PFtB phenyl sulfone as a new source of PFtB anion, which reacts with arynes in a highly regioselective manner to afford perfluoro-tert-butylated arenes in high yields. The application of the method is demonstrated by the preparation of sensitive 19F-labeled NMRprobes with an extraordinary resolving
